' Be it knownfthat 1, ANDREW A. KRAMER, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Sheet- Metal Buildings; and I do declare the following tobe-a full, clear, and exact description of the invention, such as will enable othersskilled in the art, to which it apper tains to make and use thesame, reference being bad ,to'the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification,

My invention relatesto sheet metal buildings, and more particularly to a Structure of thatcharacter adaptable for. use as a garage or shedfor housingimplements or vehicles, the principal object of the'invention being to provide a structure which may be built'up in sections, and that may be com bined in a manner to render the, structure weather proof and of substantial rigidity.

lltis also an object of the invention to provide a structure of this character which is stifiened by What I term box joints whlch not only afi'ord reinforcing and .stifiening elements to the structure but also afl'ord means for securely connecting the sections of which the building is formed in a man ner to seal the joints against wind and rain. It is also an object of the invention to provide a box joint structure which may be bent at the corners of the building and-ridge of the roof without splitting" or breaking the box rib.

In accomplishing these and other objects of the invention l have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein a Figure 1 is a perspectiye view of a sheet metal building constructed according to my invention, indicating the placementof one V of the sections.

draw- 1 designates the building as'a whole, which comprises the sides 1', roof 2, closed rear end 4, hinged front,do0rs5-6, the front roof panel 7, andthe windows 8,-a1l of which,

except the windows, areconstructed of sheet metal and combined to form a building structure. The said wall members. are madeup of separate sections of say thirty inch width, and provided with box ri-bsfl, which may be formed in a press or brake and com- I Patented June 12, llttt t.

prise outstanding ribs, preferably square in,

cross section and all of the same dimensions so that a r1b in one section may spread over a rib in another sect1on to form a jolnt, a

rib being arranged aldng each longitudinal edge of each strip so that joints may be formed at the meeting edges of the strips;

The roof is also formed in sections of the 4 samewidth as the side sections, and has ribs 11 correspondin to ribs9 in the'side sections, so that t ey may nest thereover to form joints in the same manner as the joints are formed along the side walls, the roof sections being arched at the centerand curved at the edges to turn downwardly and form extensions of the upper portions of the side wall sections the overlap portions of the side wall androofsections being connected by bolts or the like 13 which extend through the overlappedparts in order to form a substantial and integral structure.

In order to stifl'en the wall and roof sections I preferably corrugate the same transversely, as illustratedin Figs. 3 to 6 inclusive, the corrugations not only serving to ridge and edge turns may be made on the roof sections, it being apparent that the presence of the box rib would render it difficult to efi'ect the bend; without some means of expansion being provided, and-it being further apparent that with the sections or strips of metal being corrugated transversely, prior to the formation of the rib, when the sheet is bent after the ribs and corrugation are in, the extra metal provided by the corrugation will enable the ribs to straighten out by taking'up such surplus and thereby efiect the bend, the metal at the bends being substantially smooth orminus the corrugations after the bending opera- 7 tion- (Figs. 5 and 6).

ioo

The back of the building is preferably formed'of continuous vertical strips of. the corrugated and box ribbed metal, so that i .there is no break between the roof and the ground, but at the front of the building I preferably provide the panel 7 that closes the structure above the door line. In this way. it is possible to provide simple doors of rectangular shape, having a combined Width substantially equal to the width of the building, so that their outer edges may be hinged to the side walls'while their inner edges may meet at the center of the door opening.

The doors are preferably hinged to narrow panels 14:, having backturned flanges 14; bolted to adjacent side wall strips and 2 points,

preferably have box ribs 9 nesting over the end ribs 9 of said strips and extended a short distance along the side walls.

In order to further simplify the construction so that an additional piece for forming a stop for the upper edges of the doors may be unnecessary,== I turn the lower edge of the roof panel 7 outwardly at the upper door line and backwardly to form the double flange 15, the rear edge of the under ply of which is turned down and then upwardly to of angle iron to which the lower edges of the wall sections may be secured by bolts 23, and

- above the seat members I attach channel 'irons 24 to the said side wall sections in order to stiffen the walls at intermediate the channels preferably running en'- tirely about. the building and at the inside thereof and further forming supports for a shelf 25 at the rear of the building.

Windows of any suitable 1 type may be provided, those illustrated herein comprising circular openings 27 equipped with the glass panes 28 that may be pivotally mounted to swing inwardly and outwardly within the opening.

In manufacturing the building, metal strips, of proper width and length, are first run through a corrugating machine to form the transverse corrugations. They are then worked in a brake or press to form the longitudinal box ribs. The roof sections are then shaped on a suitable form, the

the sheet transverse corrugations in theroof sheet strip enabling the metal to be bent on the form, as the surplus material formed by the corrugations will enable the metal to expand in order to form the curve and being particularly advantageous in the formation of the curve over the box rib, as the metal may expand and straighten out the col rugations gradually in order that the metal may turn to the proper shape.

When the building is to be erected, two

side wall sections are connected with one roof section to form a unit, as illustrated in Fig. 1, and the said sections are bolted or riveted together in order to form the integral structure. 1 When the units are formed they may be erected so that the box joints overlap and may be bolted together, each section being arranged and connected successively until the building has reached the desired length. The end strips may then be applied toone end of the building and the roof panel to the other, and the interior stifl'ening channels and the base seat connected with the side walls as before described.

The doors are then hung, with the hinges at the front ends ofthe side wall sections and the windows installed.

It is apparent that a building of this construction may be manufactured and erected at small cost and will afford a substantial structure within which to house vehicles or implements. It is apparent that by suitably coating the metal its life may be prolonged indefinitely and that the shelter can be taken down to be moved in sections if desired.

Having thus described my invention, what I claim as new therein, and desire to secure by LetterdPatent, is

-1. A building comprising side wall and roof members, each composed of initially independent stri s of sheet metal, corrugated transverse y and box ribbed longitudinally, the roof sections being bent to form a ridge through the body portions and box ribs, and the box ribs on the roof nesting with'the box 'ribs on the side wall sections. I Y

1 2. A sheet metal structure comprisin side wall and roof sections, made of initia y independent sheets of metal, corrugated transversely and box ribbed longitudinally, the roof strips being bent to form rid e and edge portions, the side wall and roo strips having box ribs along their longitudinal edges, with the edge ribs on one section nesting with like ribs on an adjacent section and with the .ribs of. the roof strip nested with ribs of the side wall sections.

In testimony whereof I aflix my signature.

ANDREW A. KRAMER.
